MANTLE AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. '7 51,856, datedFebruary 9 1904.

Application filed May 2, 1903. Serial No. 155,284. (No model.)

To all whmn it 7mm concern:

Be it known that I, WILLIAM G. HUGHES, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMantles and Supports, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in mantlesand supports; and the object of the invention is to construct a fiat-topmantle and to provide novel and effective means for the convenientsupporting of the same.

Briefly described, my invention comprises an incandescent mantle whichis of substantially equal diameter throughout, the upper edge of themantle having a crimp to engage over lugs carried on the upper end ofthe mantle-support. The mantle-support is composed of clay or clay andother refractory material, being somewhat conical in form, with itssmaller end extending downwardly and seated in a socket providedtherefor and supported by the gauze of the burner-tube. In connectionwith my improved -support I may make the same hollow, whereby to extendthe vapor-tube therethrough, and thus heat the vapor prior to its beingdischarged at the point of ignition in the burner.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which Figure 1 is a central vertical sectional view of thepreferred form of mantle and support. Fig. 2 is a central sectional viewof a modified form of construction. Fig. 3 is a top plan view of themantle-support.

In the accompanying drawings, 1 indicates the burner, on the upper endof which is fitted a sleeve or ring 2, which carries a burnergauze 3,this burner-gauze at its inner annular edge carrying a ring 4:, whichfits in the groove 5 provided therefor in the periphery of the socket 6,which socket forms a seat for the mantle-support 7. In order to firmlybrace and secure the supporting-socket 6, I preferably provide the gauze8 below the gauze 3 and through which the socket 6 extends. The mantle 9is of substantially equal diameter throughout, and instead of having itsupper end drawn together and tied, as in the usual form of constructionwith incandescent mantles, the edge of the mantle at the top is simplycrimped over, as shown at 10, and this crimped edge lies upon the lugs11, formed integral with the mantle-support 7, peripherally of the upperend of the latter.

In Fig. 2 I show a mantle-support 7 provided with a central openingextending therethrough from end to end, whereby to receive thevapor-conducting tube 12. In such construction the mantle-support may beseated on top of the supporting-socket 6, the latter in thisconstruction being hollow and connected to or made a part of theconductingtube 14, which discharges the vapor into the burner at asuitable or desired point. With this construction of device, whichpermits of the conducting of the generated vapors through the mantle,these vapors are discharged into the burner in a highly-heated state,and the combustion is materially increased.

In construction the mantle-support is made of a composition whichpractically becomes incandescent under the heat, and the tapered shapeof this mantle serves to throw off the rays of light to all sidesthereof.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with the burner, a socket, gauze interposed between theburner and socket, a mantle-support having its upper end enlarged andprovided with lugs projecting beyond its sides, and a mantle having itsupper edge crimped over said lugs.

In testimony whereof I afiix my signature in the presence of twowitnesses.
